Description

Full or partial satin-matte glass on one or both sides with a completely homogeneous, uniform finish, smooth feel and pleasing appearance

technical field

The object of the present invention is a satin-matte finish glass with completely homogeneous, uniform finish, silky and smooth touch and pleasing appearance characteristics. With specified values for transmittance, absorbance, reflectance and roughness, a series of photomicrographs were taken using an atomic force microscope to observe the morphology and structure of the satin glass, as well as some of its physical properties.

These satin-matte finished glasses are used in the glass industry and in construction.

Background of the invention

The present invention relates to a glass with an integral or partial satin-matte finish on one or both sides produced by the method of patent MX 258791, the resulting satin-matte finished glass having a completely homogeneous, uniform finish Smooth, silky and smooth touch and appearance characteristics that look pleasing to the eye. With specified values for transmittance, absorbance, reflectance and roughness, a series of photomicrographs were taken using an atomic force microscope to observe the morphology and structure of the satin glass, as well as some of its physical properties.

Different types of satin-matte finished glasses exist, but none of them have the characteristics of one or two-sided integral or partial satin-matte finished glasses produced by the method of patent MX 258,791.

For the production of satin-matte finished glass by the traditional method, the following process is carried out: the glass block is placed on a special table showing only the top surface of the glass (this is the large surface), and the wax is placed on it. In the peripheral edge, a slurry or acid solution is placed on it to obtain a satin-matte finish; the acid is allowed to act for a certain period of time and then removed by a final wash of the glass block, one at a time, resulting in The finish is not uniform in the treated surface. With this process, it is not possible to treat the tinned side of the glass sheet, since the residues adhering to this side will not allow the standard solution used to attack.

Contents of the invention

The present invention relates to a glass with an integral or partial satin-matte finish on one or both sides produced by the method of patent MX 258791, the resulting satin-matte finished glass having a completely homogeneous, homogeneous Finished, silky and smooth touch and desirable appearance. With specified values for transmittance, absorbance, reflectance and roughness, a series of photomicrographs were taken using an atomic force microscope to observe the morphology and structure of the satin glass, as well as some of its physical properties.

Glass with integral or partial satin-matte finish on one or both sides is fully or partially satin-matte on one or both sides of glass sheets by immersion in an acid solution according to patent MX 258791 for simultaneous and continuous production Products obtained by surface finishing chemical processes.

Glass with one or two sides integral or partial satin-matte finish is obtained from flat glass sheets of any sheet thickness, color and size.

The characteristics of the satin-matte finish glass of the present invention surpass that of satin-matte finish glass produced by other methods in which the satin-matte finish is applied to only one side of the glass sheet.

The sheets of flat glass used are complete sheets with commercial dimensions from 180x160cm up to 3600x2600cm, including special measurements and thicknesses from 2mm to 19mm, and different glass colors like clear, green, grey, blue, brown, filter, etc. Satin-matte finish is applied on one side (independent of tined (tined) or atmospheric side) or on both sides at the same time with the whole (one or more complete sides of the glass sheet) or part (such as graphic , blots, stripes, etc.) to obtain a very uniform finish at a lower cost than uneven finishing of only one side by other methods.

Conduct transmittance, absorbance, reflectivity, and roughness tests on one or both surfaces of the present invention with integral or partial satin-matte finishing glass, and use an atomic force microscope to collect a series of photomicrographs to observe the satin glass morphology and structure, as well as some of its most important physical properties.

The satin-matte test for transmittance, absorbance, reflectance and roughness is shown in Table A below, and a series of photomicrographs were collected using an atomic force microscope to observe the morphology and structure of the satin-matte finished glass of the present invention.

Results and conclusions

Results for clear satin glass:

The transparent satin glass on both sides reduces the visible light transmittance: from 87% of the glass with a thickness of 2mm to 77% of the glass with a thickness of 9.5mm, and the transmittance decreases gradually as the thickness increases. If it is just one side, there is no significant reduction in transmittance, but it is higher at 6mm thickness, so that in the case of satin finish on the tin-plated side, it reaches a value similar to 9.5mm (76%); and when only dealing with the large surface , reaching 84%.

However, for wavelength values in the infrared range (1100 nm), the transmission decreases steadily from a value of 80% for a glass of 2mm thickness to a value of 63% for a thickness of 6mm. A similar situation occurs when only one of the two faces is treated, although for a thickness of 6mm the reduction in transmission reaches 53%.

Satin results for different types of glass:

If satin is applied to different types of glass, using a thickness of 6mm as a reference, smooth glass shows visible light transmission ranging from 80% for clear glass to 40% for gray satin glass.

In particular, for the green satin glass, the infrared transmission is reduced even more (12%) from the 70% transmission value shown by the same satin glass in the case of visible light. The blue satin glass also shows a significant change in transmission: 54% for visible light and 31% for infrared.

A similar trend was observed for glasses with a satin finish on only one of the two faces. Roughness results for different types of glass:

The roughness of the glass samples was measured using a TR Surface Roughness Tester under the trademark Time.

A remarkably uniform roughness can be observed from the photographs, so that the resulting satin-matte finished glass has a completely homogeneous, uniform finish, silky and smooth touch and a pleasing appearance, other similar satin finishes Glass does not have these properties.

Advantage

From the results obtained and the thermal characteristics of the tests carried out on the smooth glass of the present invention, it is surprising to obtain a satin glass with excellent solar light harvesting properties for photovoltaic cells and solar heaters, because we can understand the electromagnetic spectrum Different types of filters for different wavelength ranges apply different treatments. In the satin-matte finish on both sides of the glass sheet, a glass with excellent properties as a thermal insulator is obtained, which does not allow the passage of infrared rays but allows the passage of visible and ultraviolet rays.

It can be used in the construction industry, residential, decoration and glass industry, etc., where it is required to have an extremely uniform finish, silky and smooth touch and appearance, and has a specified transmittance, absorbance, reflectivity and roughness. Satin-matte finish glass with a high degree value, other satin glasses currently known do not have these properties.

It should be pointed out that the best method of carrying out the invention known to the inventor so far is apparent from the description of the invention.

Ii) immerse the acid solution that is used for satin light-matte finish; It comprises 3% to 8% 70% hydrofluoric acid; Be equivalent to total hydrofluoric acid of 2.1% to 5.6%, 3% to 8% 30% hydrochloric acid; Be equivalent to total hydrochloric acid of 0.9% to 2.4%, 10% to 30% 85% formic acid; Be equivalent to deionized water, 20% to 50% anhydrous hydrogen fluoride ammonium and 5% to 25% sugar one DEXTROSE MONOHYDRATE of total formic acid of 8.5% to 25.5%, 20% to 40% at least 10 micro-ohms, immersion speed is 5.2 meters/minute, and soak time is 5 minutes to 30 minutes;

Iii) soak to wash and to remove the residual of previous acid solution, this carries out through spending deionized water spray then in the immersion water;

Iv) soak to stop chemical reaction on glass; And remove the acid traces solution that might exist, 30% hydrochloric acid that it comprises 3% to 5% is equivalent to total hydrochloric acid of 0.9% to 1.5%, 3% to 5% 70% hydrofluoric acid; Be equivalent to 2.1% to 3.5% hydrofluoric acid and 95% to 97% water; This solution should be every liter of 0.5 to 1.0 milli-equivalent, 2.1 to 3.2 pH value, and soak time is 30 seconds to 3 minutes according to sheet glass quantity;

V) soak to wash and to remove above-mentioned acid solution, this spends deionized water spray then and accomplishes through immersing in the water;

Vi) and vii) soak the residual stage with washing and removal acid solution, this spends deionized water spray then and accomplishes through immersing in the deionized water; With

Viii) any maybe or necessary situation under, can water or acid solution soak.

31. satin light according to claim 29-matte finish glass; Be characterised in that; The drying of glass block and/or sheet is carried out in the kiln of 30 to 60 ℃ of temperature, perhaps also can carry out at ambient temperature, perhaps horizontal or vertically through washer/moisture eliminator; Perhaps pass through tunnel furnace, and do not influence glass quality with Sweet natural gas, LP gas and/or resistance operation.
